Thomas Tuchel is hopeful that Mason Mount could return to Chelsea training this afternoon and be in contention for a place in the Blues squad to face Lille, along with Cesar Azpilicueta.
Mount, Azpilicueta, Callum Hudson-Odoi were absent from the Chelsea squad that defeated Crystal Palace 1-0 at the weekend.
The former suffered a ligament issue in the first half of Chelsea's Club World Cup final, while Azpilicueta missed training with a groin problem. Winger Hudson-Odoi had inflammation in his achilles keeping him out of the trip to Selhurst Park. The latter's involvement is looking less likely than his captain's.
